Is the USS Little Rock sleepover a Council sponsored event? If so, I believe that affords you some protection in the event of problems.
Has your Pack Committee discussed the event and shared all the details, including the sleeping arrangements, with the parents? If some are uncomfortable they can opt not to attend.
Our Pack has done sleepovers on battleships (USS Massachusetts, sleeping like the sailors in hammocks), museums (Boston Museum of Science and Plymouth Plantation, both very popular, folks bed down all over the floors of the exhibit halls), and cabins. All of these have seen mixed sleeping arrangements with male and female leaders and parents, the boys, and sometimes siblings (boy/girl) all together in a large space. In the case of the museum and battleship, all Council sponsored events with separate rest room/changing facilities, we were participating with many other packs and troops. In the cabins sheets and tarps were used to make privacy areas for changing. In all these cases we havent had any problems with impropriety, only my snoring (well, not JUST me).
In our Pack's case no one person was making a common sense decision on his or her own. With all these events our Pack Committee and Leaders discussed the details and options, shared this information with the parents, and I guess you could say a common sense by consensus decision was made concluding that, by attending the event, the benefit to the boys would far outweigh the potential for problems. If someone complains later on, they cannot deny that they were unaware of what they were getting into.
I concede that this is a litigious age we live in but, as it has been said in this thread, you cant foresee every danger. If we worried about every eventuality the boys would do nothing. I agree that good common sense is key, but a fully informed pack is also important. MOST people are not unreasonable as long as they know what theyre getting into and can prepare for it.
It seems a shame that the boys have to suffer for adult paranoia. If the sleepover is anything like our USS Massachusetts experience, theyll have a ball.
